"During extremely high-capacity times, like during the campaign, I went into survival mode: I worked and I was with my family; I didn’t do much else," Ms Trump writes, according to an excerpt published by Fortune.

"Honestly, I wasn’t treating myself to a massage or making much time for self-care. I wish I could have awoken early to meditate for twenty minutes and I would have loved to catch up with the friends I hadn’t seen in three months, but there just wasn’t enough time in the day."

Since entering the White House, she has continued to share pictures of her three children on social media. One of those posts was a video of her daughter singing Mandarin, a clip that was widely praised in China - just a few days after the president had irked Beijing by failing to send greetings for the Lunar New Year.

However, Ms Trump, who still owns her fashion business via a trust, admits in the book that she initially worried about sharing such pictures, fearing she would not be taken seriously in the business world.

She later wondered whether she might be "doing women who work a disservice by not owning the reality that, because I’ve got an infant, I’m in my bathrobe at 7 a.m. and there’s pureed avocado all over me".

"I realised that it might be helpful in changing the narrative - even in a small way -to, for example, debunk the superwoman myth by posting a photo that my husband candidly snapped of me digging in the garden with the kids in our backyard, my hair in a messy ponytail, dirt on my cheek. I’ve been careful not to pretend it’s easy because it is not."

Much of her second book, Women who Work, Rewriting the Rules for Success, was written before Mr Trump's election victory, but she has held high-profile summits on women in the workplace since entering the White House.

"Knowing my family is in the spotlight, I decided I was going to embrace it. If I can help celebrate the fact that I’m a super-engaged mom and unabashedly ambitious entrepreneur ... I’m going to do that," she writes.

"Together we will debunk the caricature of what it looks like to be a 'working woman'."
